Smart Phone Lock - Lockscreen

Description
Are you worried about exposing your PIN and Pattern while you unlock your phone?
Here comes Smart Phone Lock for the rescue.
Smart Phone Lock will set the current phone time as your unlock PIN for the lock screen. It will change the PIN magically on every minute! So, each time you unlock the device, the PIN will vary and you need not worry about prying eyes around you. The best part is, you need not memorise anything to remember the PIN. The modifiers will allow you to enhance the security to the next level.
Modifiers :
1) Offset PIN - You can set a number (Positive/Negative) and that number will be added/Subtracted from the current time.
Lets say the time is 03:30 and the offset is +10, then the current unlock code will be 0340.
2) Reverse PIN - If you enable this modifier, then the PIN is reversed number of the current time.
Lets say the time is 03:50 and the PIN to unlock the lock screen is 0530.
